[0002] The automatic detection device for oxygen content in a sewage pool is a device used to detect the oxygen content in a sewage pool. It is usually composed of an automatic detector, an optical sensor and a display. It can monitor the oxygen content in the sewage pool in real time and display the data so that the oxygen status in the sewage pool can be understood in time.

[0003] When the automatic detection device for oxygen content in the sewage pool is used again, it is necessary to connect the optical sensor to the automatic detector through a cable, and then place the optical sensor in the sewage pool to detect the oxygen content, and then transmit the data to the controller for processing, and alarm or control according to the set threshold, so as to effectively improve the efficiency and quality of sewage treatment, reduce pollution to the environment, and improve the safety and reliability of water quality.

[0031] Further, the mounting block 203 on the surface of the waterproof cover 201 is aligned with the mounting groove 202, and then the pull plate is pulled to drive the moving rod 206 to move upward. When the moving rod 206 moves upward, the spring 207 is compressed, and the positioning rod 205 is further driven to move upward from the positioning groove 204. At this time, the mounting block 203 on the lower surface of the waterproof cover 201 is used to make the mounting block 203 cooperate with the mounting groove 202, so as to install the cable 102, so that the positioning rod 205 and the positioning groove 204 can cooperate to strengthen the installation firmness of the mounting groove 202 and the mounting block 203, thereby strengthening the installation firmness of the cable 102 and the interface 101, and avoiding the staff from placing the optical sensor 303 in the sewage pool to move it, causing the cable 102 to be pulled, and the cable 102 and the interface 101 to separate from each other, thereby ensuring the normal use of the cable 102 and the accuracy of the transmitted signal, so that it will not affect the accuracy of the measurement structure.

[0032] Example 2

[0033] Reference Figure 1 , Figure 2 and Figure 5, which is the second embodiment of the utility model. This embodiment is based on the previous embodiment, and a placement component 3 is provided on the outer surface of the housing 1.

[0034] Specifically, the placement component 3 includes a placement plate 301 fixedly installed on the outer surface of the shell 1, a protective plate 302 is fixedly connected to the upper surface of the placement plate 301, an optical sensor 303 is movably connected to the upper surface of the placement plate 301, a dust cover 304 is fixedly connected to the outer surface of the shell 1, a rotating rod 305 is rotatably connected to the inner wall of the dust cover 304, a cable 102 is wound around the outer surface of the rotating rod 305, and the other end of the cable 102 is fixedly connected to the outer surface of the optical sensor 303.

[0035] Furthermore, the optical sensor 303 is placed on the surface of the placement plate 301, and the protective plate 302 on the upper surface of the placement plate 301 can prevent the optical sensor 303 from sliding off the placement plate 301 to the ground, thereby ensuring the normal use of the optical sensor 303 and the accuracy of signal transmission, reducing the cost and time of maintaining the optical sensor 303, and at the same time, the cable 102 can be placed on the surface of the rotation rod 305 for storage by rotating the rotation rod 305, and the dust cover 304 can prevent dust from entering the rotation rod 305 and the surface of the cable 102, so that the cable 102 can be easily stored, avoiding the cable 102 from being entangled into a ball that affects its signal transmission, and reducing the wear of the cable 102 when it is entangled.

[0036] Working principle: When in use, the housing 1 is placed next to the sewage pool to be inspected through the support pad, and then the waterproof cover 201 and the cable 102 are matched, so that the waterproof cover 201 can be installed on the surface of the cable 102, and then the mounting block 203 on the surface of the waterproof cover 201 is aligned with the mounting groove 202, and then the pull plate is pulled to drive the moving rod 206 to move upward. When the moving rod 206 moves upward, it will drive the spring 207 to be compressed, and further drive the positioning rod 205 to move upward from the positioning groove 204. At this time, the mounting block 203 on the lower surface of the waterproof cover 201 is used to make the mounting block 203 match the mounting groove 202, so that the cable 102 is installed and matched with the positioning rod 205 and the positioning groove 204. The installation firmness of the mounting groove 202 and the mounting block 203 can be strengthened, thereby strengthening the installation firmness of the cable 102 and the interface 101, and preventing the staff from placing the optical sensor 303 in the sewage pool and moving it, which causes the cable 102 to be pulled, and the cable 102 and the interface 101 to separate from each other, thereby ensuring the normal use of the cable 102 and the accuracy of the transmitted signal, so that it will not affect the accuracy of the measurement structure, and then the optical sensor 303 is placed in the sewage pool and moved, so that the optical sensor 303 detects the oxygen content in the sewage pool, and then the detected data is transmitted to the housing 1 through the cable 102, and the oxygen content in the sewage pool is detected through the housing 1.

[0037] After use, the optical sensor 303 is taken out of the sewage pool, and then the optical sensor 303 is placed on the surface of the placement plate 301. The protective plate 302 on the upper surface of the placement plate 301 can prevent the optical sensor 303 from sliding from the placement plate 301 to the ground, thereby ensuring the normal use of the optical sensor 303 and the accuracy of signal transmission, reducing the cost and time of maintaining the optical sensor 303, and at the same time, the cable 102 can be placed on the surface of the rotating rod 305 for storage by rotating the rotating rod 305, and the dust cover 304 can prevent dust from entering the rotating rod 305 and the surface of the cable 102, so that the cable 102 can be easily stored, avoiding the cable 102 from being entangled into a ball and affecting the transmission of its signal, reducing the wear of the cable 102 being entangled together, thereby indirectly extending the service life of the cable 102.
